Apache VirtualHost multiple domain multiple SSL - apache

Question

Hi I have the following use case, I have an application (let's call it foobar) on a remote server /var/www/foobar and I have the following Apache VirtualHost conf
<VirtualHost *:80>
DocumentRoot /var/www
# This is to redirect http traffic to https
Redirect permanent / https://example.com/
</VirtualHost>
<VirtualHost *:443>
SSLEngine On
SSLCertificateFile /etc/ssl/certs/example.com.crt
SSLCertificateKeyFile /etc/ssl/private/example.com.key
SSLCertificateChainFile /etc/ssl/certs/example.com.bundle.crt
ServerName example.com:443
DocumentRoot /var/www/foobar
</VirtualHost>
And its working all fine. Now suppose I have another domain example2.com and I want it to point to the same foobar application. My current thinking is create another VirtualHost below, something like this
<VirtualHost *:443>
SSLEngine On
SSLCertificateFile /etc/ssl/certs/example2.com.crt
SSLCertificateKeyFile /etc/ssl/private/example2.com.key
SSLCertificateChainFile /etc/ssl/certs/example2.com.bundle.crt
ServerName example2.com:443
DocumentRoot /var/www/foobar
</VirtualHost>
But I was wondering is this the correct way of doing stuff like this? I need both domains to be "independent" so I didn't make a permanent redirect from example2.com to example.com

Answer 1

You can do something like below,You can use the server alias for this, Also I don't see anything wrong in having 2 virtual hosts as well.
<VirtualHost *:443>
ServerName example1.com
ServerAlias example2.com
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html/testlink
</VirtualHost>
If you are getting unable to get a certificate error, you can create a certificate with a wildcard CN. e.g : *.comthis will match both example1.com and example2.com.
